My friend invites me over for a movie night with his family and I happily accept, especially when I found out his sister was going to be joining us that night. I honestly can't remember what the hell we watched because his sister came out wearing a tight tank top and a pair of loose gray shorts. They hung down low but the legs were cut wide.

The family all had their favorite spots and the seating was arranged in a horseshoe pattern and everyone was facing the TV. I took one side of the love seat and his sister sat down next to me with a blanket. No one said a word about the arrangement and shortly after the lights were turned down and the movie started. It was a pretty large room with a big TV and surround sound and everyone else was positioned in front of the love seat. Which meant no one was looking at us as the movie started.

As soon as the lights went out she started rubbing her hand up and down my leg and sliding it up my shorts. I got super nervous and looked at her because what if someone saw. She smiled sweetly and got up and walked out of the room. She came back shortly with a blanket and promptly covered us both up. She took my hand and moved it up her shorts and I found she was not wearing panties and was very clean shaven. I immediately started rubbing her pussy as we sat there but she moved my hand out from the leg of her shorts and had me move it down the back of them. She sat up a little and I moved my hand down and under her ass until my hands were cupping her pussy and she was sitting on my arm a little. She started grinding her self against my fingers and I slipped a couple inside of her. She was getting super wet and I could hear her making little noises. Thankfully no one could hear over the movie when she finally came all over my hand.

The entire time she was riding my hand she kept teasing my cock through my shorts but she wouldn't touch me. I kept trying to get her to but she would always just stop short of actual skin to skin contact. When she came on my hand I was so hard and aching I would have fucked her right there of we had been alone. She lifted her ass and I slid my hand out of her shorts and got up to go use the bathroom.

The bathroom was right down the hall and while I was in there I heard someone else walking down the hall. I opened the door to go back and found her standing there. She pushed me in and we locked the door again. She started kissing me and tugging down my shorts until she got my cock free. She started sinking down on her knees but I was too aroused for that and having felt her pussy I knew what I wanted.

I pulled her up, turned around to face the mirror and yanked her shorts down. Her eyes went wide as she looked back at me and felt me rubbing my cock up her inner thighs but she smiled and bent forward enough for me to slide inside of her. She felt absolutely amazing and knowing we didn't have a lot of time I started taking her hard and fast but as quietly as we could.

She was gripping the sink and watching me fuck her in the mirror. It didn't take long for either of us to get close to cumming and she turned the water on high right as she did. I fucked her through it and about the time she finished I felt myself clench up and I buried myself deep and had my own orgasm. After we both finished I pulled out and a large amount of cum slipped out down her thighs. She turned around and smacked me for the cream pie and then kissed me again before wiping herself and leaving the bathroom.

I got back to the living room and no one seemed to care or notice because of the movie. She came back a little later wearing a different pair of shorts. I found out later she had to change because her shorts were soaked in my cum and she had to put on a pair of panties because she kept leaking from the amount inside of her.

That started our experiments with public sex and seeing what we could get away with.
